IMPROVEMENT IN MODES 0F SECURING IRON RAILINGS T0 THEIR POSTS.

Specification forming part of Letters Patent No. 38,049, dated March 31, 1863.

To all whom, it may concern:

. Be it known that I, SAMUEL MAGEEREAN, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Securing the Panels of Iron Railings to their respective Posts; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in Which- Figure] represents a panel of railing attached to its respective posts by the improved method. Fig. 2 is a longitudinal section on an enlarged scale of the combined pin and nut, and a portion ofthe rod B, to which it is attached. Fig. 3 is a transverse section ofthe same.

Like letters in all the figures refer to the same parts.

The nature of my invention consists in a combined pin and nut for securing panels of ironrailings to their respective posts, constructed and arranged in the manner I will hereinafter describe.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the ordinary method of securing the panels of railings to their respective posts, when the different sections of the panels are held together by longitudinal rods, the ends of the rods enter corresponding holes in the sides of the posts, and are secured by means of nuts in the hollow7 or perpendicular opening of the posts. This makes it necessary to cast the posts in several pieces, which are secured together by vertical rods to enable them to be taken apart to insert a wrench in theinside of the posts to screw and unscrew the nuts on the ends of the rods, and consequently increased expense is incurred and trouble experienced in adapting the posts to this system of fastening and detaching and securing their parts together. Now, instead of passing the ends of the wrought-iron rods B through the sides of the posts A and securing them thereto by means of nuts inside of the posts, as heretofore, I form on the ends of said rods B screw-threads, on which the nuts are screwed, for the purpose of securing the panels to the posts, and', in lieu of the nuts heretofore employed for the purpose, I provide nuts C, which may be made of either round, Octagonal, or other form, and combine with the said nuts coupling-pins D, which are at right angle to the screwholes of the nuts, and which pro ject about an inch and ahalf, more or less, from the peripheries of the nuts. In addition to this special design the pins act as' purchases for screwing and unscrewin g the nuts, andin thus dispensing with the use ofthe wrench the progress of the work is much facilitated. The combined thickness of the several rings, E, for conning the sections of the panel on the horizontal rods B is such as to bring the coupling-pins D in vertical position, when the nuts G are screwed tight to enable them to drop readily into corresponding vertical openings in projections or lugs F on the sides of the posts A, and in this manner to secure the panel in its proper position between the posts, when the latter are firmly planted on their bases. The combined pin and nut C D, I usually make of malleable iron; but, if desired, they may be made of wrought-iron, the pin being screwed or otherwise fastened in the side of the nut.

From the foregoing it will be observed that the panels of the railings can be attached and detached from their respective posts A by the simple act of lowering and raising the same, so as to drop the coupling-pins D on the nuts G into and lift them from the openings in the lugs F, and that the trouble and expense before referred to in the old system are in this case entirelyavoided. In case it is desired, the coupling-pins D on the nuts (l of either the lower or upper rod, B, may have threads and nuts on them to more firmly secure the panels to the posts.

It will readily be seen that my combined pin and nut is notonly adapted to securing panels to the posts, when the former are made in sections and attached to horizontal rods, but also when the panels are in single pieces, which, should they not have rods extending their whole length, may have pins projecting from their ends to receive the nuts. The plan of combining the combined pin and nut to the panel may be indetinitelymodiiied to suit any peculiar construction of the latter.

I hang gates to their posts by means of the i ranged, `and operating substantially in the combined pin and nut, arranged on the edge In testimony thatvtlie above is my invention 0f the gate in the same manner as on the staf I have hereunto set my hand and affixed my tionary panel above described. seal this 15th day of .April7 1 862.
